T 0 all whom it may concern:

I Be itknown that I, JAMES A. JoHNs'roN', a citizen of the United States, and resident of the city otSeattle, in the county ofKing and State of Washin ton, have invented certain new and useful mprovements in Toilet- Fixture Connections, OffWhlCh the following is a specification. Q

My invention relates particularly to'water closet drain connections.

' Th object of my inventionis to provide a toilet fixture drain connection which is capable of being tightly sealed in both the toilet and the drain pipe so that there is no possibility of leakage of drain water or, sewer gas, and which will form aconnection in which, the parts will not become separated and leak after a period of use.

Another object of my invention is to pro; vide a connection of the character described which Will be sufiiciently fiexibleto admit some variation inspacing between theintake end of the drain pipe and the outletof the toilet fixture. V

Anotherj object of my invention is to. pr0-' vide a water closet fixture, which would generallybe made of porcelain, in such a shape that it will not need to be provided with a projecting outlet pipe, which is liable to be broken in shipment, in the forms now inuse. My inventioncomprises the novel parts and combinations thereof which are shown in the accompanying drawings, described in the specification, and particularly defined by the claims. I In the accompanying drawings 1 have shown my inventionin its present preferred forms. I I Figure 1 is, a sectional view through a portion of a toilet fixture and the drain pipe showing the manner of securing my connection in place.

Fig. 2 is a similar sectional view of a' slight modification of construction.

Fig. 3 is a sectional View showing another modification. i In' the style of water closet connections now in use'the connection of the water closet with the drain pipe or soil pipe, after a short period of use, becomesloose and permits leakage of drain water and of sewer gas. Partially this fault is due to the mar a d i he Packi g ket an it is par ia ly du to" the Qrm' f onnection with the water closet and'the drain pipe;

Specification of Letters Patent. Patented Aug. 80, 1921. Application filed Ja uar 21, 1920. Serial No. 352,919. I

In fitting such a fixture into ahouseit is outlet of thewater closet fixture andpthe opening of the drain pipe in any two installations. To provide for this variation and to insure'permanently tight joints both with the drain pipe and with the water closet fixture I. have provided the type of connection shown and described in this application. y The water closet 1 may be of any suitable construction except that about its outlet 10 I form in; itafldeep annular groove 11. I prefer also hat the lower end of the outlet 10 should not project below thefleyel of the floor flange 12. "The soil 'pipe or drain pipe 2 is bentupwardly where it isintended to be connected with the toilet fixture, and about its upper end 20 is formed a collar 21. Preferably the collar 21' would be outside of the upturned end .20 of the drain pipe, thus forming between itself and the end 20, an annular groovef22, p

In fitting such a fixture in the house the drain pipe 2 is first secured with its end 20 beneath the position which will be. occupied by. theoutl'et 1001 the. fixture 1. A separate withone sideof the groove 22. As shown I in Fig. 1, and as I prefer to make it, the snug fit is between the jsleevefil and the collar 21. The collar 2l'shiould be spaced from the end 20 of the pipe enough to permit pouring of sealing .m'at'erial between-the end 20 aiter the pipe section 3 is in'place. I v p deep enough to permit considerable variation in the positionor' the lower end of the The groove22 should be sleeve 31fther ein. This permits variation in the spacing between the end 20 of the ,drain pi 3e the outlet 10 of the fixture 1 to be ta en careof in fitting the fixture'in a house. :After theisleeve'31 isfitted into the collar 21 a suitable seal, preferably of poured metal, as lead, may be poured from the inside of the pipe section 3 and will occupy the space as shown at 33 beneath the sleeve 31 and between this sleeve and the end 20 of the drain pipe. This seal, in the preferred construction, may be poured from above, through the pipe section 3, making it possible for the plumber to see what he is doing, and greatly facilitating the work. The fit between the sleeve 31 and collar 21 is tight enough to prevent leakage of the metal being poured.

The floor flange 32 of the pipe section 3 may be secured. to the floor before sealing the sleeve 31 in the groove 22, as by means of screws 34. After the section 3 has been secured to the drain pipe the toilet fixture 1 may be secured in place upon it. The upper sleeve 30 is adapted to form a close fit within the groove 11 about the outlet of the toilet fixture. The sleeve 30 should be of such a length that its upper end comes nearly to the bottom of the groove 11. The remainder of the space may be filled with any suitab e form of gasket, as shown at 35. I prefer that this gasket should be made of a resilient, but non-shrinking material. I have found compositions known as litharge and glycerin, or lubricated asbestos, to be suitable for the use intended. i

The gasket 35 serves to securely seal the connection against sewer gas and should be of a material that will not deteriorate, shrink or break with use. However, if such matter is not used, by making the groove 11 very deep and the fit of the sleeve 30 therein a close one, a relatively inefiicient gasket at 35 will serve to seal in the sewer gas. Also the construction of the groove 11 serves to prevent leakage of the drain water, as the water will not be under suflicient pressure toforce itself up between the sleeve and groove.

The fixture may be secured to the section 3 by means of bolts 13 or to the floor by means of the bolts 14. After it hasbeen placed upon the sleeve 30 with the gasket 35 resting upon the upper end of the sleeve 30 the pipe section 3 and the fitting 1 should be pressed-together to compress the gasket 35 and to cause it to fill the available space at the upper end of the sleeve 30.

The connection thus described forms. a joint which is tight and secure against drain water and sewer gas both in its connection 'with the toilet fitting and with the drain pipe. The connection with the drain pipe is of such character as to permit variation in the position of the upper end I of the pipe and to facilitate its installation. In addition, the pouring of the seal 33 from the inside of the pipe connection 3 without any packing between the sleeve 31 and the collar 21 permits a quicker and easier sealing of this connection fromvabove, where, if it to Work, however, the outside seal may be found more satisfactory, as shown in Fig. 3.

In Fig. 2 I have shown a construction which is similar to the construction just described, with the exception that the lower sleeve 31 of the pipe connection 3 is screwed into. the upper end 23 of the drain pipe 2 and no collar similar to the collar 21 is employedflupon the upper end of the drain pipe. This connection, however, is not so flexible as the one just described, and the former is my preferred construction.

What I claim as my invention is:

1. A water closet drain connection comprising a water closet having a deep annular.

a collar formed about the end of the drain,

pipe and forming therewith an upwardly facing annular groove, the lower end of the pipe section fitting closely within the inner side of said collar to form a tight joint, and a seal of poured' metal filling the remainder of said annular groove beneath the lower end of the pipe section and between the pipe section and the drain pipe, and a gasket compressed between the upper end of said pipe section and the bottom of the groove in the closet base to form a gas-tight joint therebetween.

2.v A water closet drain connection comprising a water closet having a deep annular groovein its base extending about and separate from its outlet, a drain pipe, a

pipe section having a radial flange adapted to be secured to the floor and to the water closet bowl, the upper; end of said pipe section fitting closely within said groove in the closet base, a gasket supported only upon the upper end of the pipe section and compressed between the upper end of the pipe section and the bottom of said groove to form a gas-tight joint therebetween, a collar formed upon the outside of the end of the drain pipe and forming therewith an upwardly facing annular groove, the lower end of the pipe section fitting closely within the inside of said collar to form a tight joint therewith, and a poured metal seal filling the annular groove beneath the lower end of the pipe section and between it and the upper end ofthe drain pipe.

3. A water closet drain connection comprising a water closet having a downwardly facing deep annular groove about its outlet, a drain pipe, a pipe section having a radial flange adapted to be secured to th floor and ioo pipe section and the upper end of the drain 10 pipe comprising a tight joint between the pipe section and drain pipe, and an'inside poured metal seal between said members and sealing said joint.
